When a Facebook friend is online, there will be an icon displayed by their name in the friend list. This also indicates that instant messaging can take place.
The Facebook can delete her/him from facebook if he/she has been reported few times. You can remove a friend from your friends list by going to a friend's page and at bottom left corner there's a Remove button.
